    Abstract: An example of a method of determining a position of a device includes: receiving, with a receiver of the device, a signal from a reference emitter; obtaining a code phase measurement of the signal; obtaining a carrier phase measurement of the signal; calculating an intermediate quantity that is a function of the code phase measurement and the carrier phase measurement; calculating a carrier phase smoothed estimate of a code phase of the signal based, at least in part, on a robust aggregation of the intermediate quantity; and determining the position of the device based, at least in part, on the carrier phase smoothed estimate of the code phase.

    Abstract: A range between a first wireless device and a second wireless device is estimated using a first mechanism based on messages transmitted over a first communication channel. The first communication channel is associated with a first radio access technology capability of the wireless devices. One or more metrics indicative of an accuracy of the range estimates provided by the first mechanism are obtained. A second mechanism to estimate a range between the first wireless device and the second wireless device may be implemented in favor of the first mechanism when the metric fails to satisfy a criterion. The second mechanism is based on unicast messages transmitted over a second communication channel. The second communication channel is associated with a second radio access technology capability of the wireless devices and may be the same as, or different from, the first communication channel.

    Abstract: Association algorithms of newly-detected lane boundaries to lane boundaries can be made more robust through the use of generated or "dummy" states. Different types of dummy states can be used to identify outlier/erroneous detections and/or new, legitimate lane boundaries. Therefore, depending on a type of dummy state a newly-detected lane boundary is associated with, the newly-detected lane boundary can be ignored, or the associated dummy state can be added to the lane boundary states of the filter.

    Abstract: The disclosure generally relates to position sensors, and more particularly to outlier detection using spatial displacement data. An apparatus for use in position sensing may include a displacement sensor, a positioning signal receiver having a receiver clock, a memory, and a processor coupled to the displacement sensor, the positioning signal receiver, and the memory. The processor and memory may be configured to calculate a change in a receiver clock bias of the receiver clock based on range measurements and spatial-based displacement data, propagate a first range measurement based, at least in part, on the spatial-based displacement data and the change in the receiver clock bias, and determine an outlier range measurement based, at least in part, on the propagated first range measurement.

    Abstract: System, methods, and apparatus are described for transmitting encoded bits over a bus by conditionally embedding dynamically shielded information. In an example, the apparatus transmits a first group of encoded bits over a bus, generates a second group of encoded bits to be transmitted over the bus, where a first subset of the second group of encoded bits are encoded to avoid crosstalk-inducing bit transitions on adjacent lines of the bus, and configures one or more encoded bits of a second subset of the second group of encoded bits to ensure that the second group of encoded bits includes parity information and/or clock information, while further ensuring that crosstalk-inducing bit transitions in the second group of encoded bits are avoided.
